OF PLANTSVILLE ASSIGNOR TO PEOK, STOW COMPANY, OF SOUTHINGTON, CONNECTICUT.

& WILGOX AP PLE-PARER.

SPECIFICATION forming part of Letters Patent No. 233,044, dated October 5, 1880.

Application filed June 9, 1880. (Model.) 7

To all whom it may concern:

Be it known that I, ORSON W. STOW, of Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Apple-Parers, of which the following is a specification.

In the accompanying drawings, Figure l is a plan view of an apple-parer which embodies my invention. Fig. 2 is 'a front elevation of the same. Fig. 3 is a side elevation. Fig. at is a vertical section, partly in elevation, taken on a plane through the knife-carrier and the axis of the knife; and Fig. 5 isa vertical section of the same, taken on a plane transversely to the horizontal axis of the knife.

The general plan of the machine, when broadly considered as one which carries the paring-knife around continuously while the apple revolves, and one which is provided with an automatic knock-off, is old; but the means for carrying and operating these devices are believed to be new.

Adesignates the frame of the machine, provided with any suitable clamping device, a, to

2 hold the frame upon any proper support.

B designates the main driving-wheel, provided with a suitable operating-crank, O. Meshing into this gear is the gear D, which carries the fork b and its shaft. By the side 0 of the fork-shaft there is a knock-off, 0, fitted to slide longitudinally with said provided with a collar, (1, which surrounds the fork-shaft, and has projecting therefrom an arm, 0. There is also surrounding the fork- 3 5 shaft a spiral spring, f, Fig. 2, for forcing the collar and the knock-off toward the gear. The main driving-wheel B is provided with a pinion, E, into the upper side of which meshes the geared wheel F, carrying upon one side the cam g, which in its revolution comes in direct contact with the arm 6 of the knock-off c, and forces said knock-off toward the end of the fork, as shown in Figs. 1 and 2, thereby pushing the apple from the fork in case there is one 4 5 upon it at the time. After the cam .g has passed the arm 0 the knock-off and arm return to the position indicated by broken lines in Fig. 1 under the influence of the spring f.

G designates the revolving knife-carrier or table, arranged to revolve on a vertical axis,

sh aft, and

and having a knife, H, jonrnaled to its under side, as shown most clearly in Figs. 4 and 5. The horizontal axis of this knife is surrounded by the spring it, one end of which is fastened to the knife-carrier G, and the other end to the arm '6 on the knife-holder, whereby the spring has a constant tendency to force the knife toward the axis of the knifecarrier. Mounted upon the stud, directly over the knife-carrier and in line with its axis, there is a stationary 6o cam, I, of the form most clearly shown in Fig.

1, and against the periphery of which the knife H continually bears under the influence of its spring.

When the knife H reaches the notch in the cam i (designated by itis in proper position to commence paring the apple. The knifecarrier G is driven by means of pinions m and a mounted upon a shaft, 0, which mesh, respectively, into the gears in the knife-carrier 70 G and the pinion E. As the knife-carrier revolves the spring will force the knife against the apple for nearly half a revolution of the knife-carrier, and until the knife has traveled substantially half-way around the apple, after which the increasing projection of the stationary cam will throw the knife backward out of contact with the apple, and as the knife-carrier continues in its movement the knife will be depressed sufficiently to pass under the fork-shaft, and as it passes the shoulder of the cam will spring into the notch k, ready to repeat its former operation.

In order to pare the apple upon the stem end as near as possible to the core, 1 provide 8 5 a supplemental paring-knife, J, the same being mounted on a stationary axis upon the stationary cam I. At the foot of this knife J there is a cross-arm, under one end of which is a spiral spring, q, and the opposite end of 9 which projects slightly beyond the greatest projection of the cam I. On the upper side of the knife-carrier G, I provide an upward-projecting cam, r, which at each revolution engages the projecting end of the cross-arm p, so as to throw the supplemental knife J into the position indicated by the broken lines in Fig. 2, thereby paring the stem end of the apple. This cam is so located with reference to the knife-carrier that the stem end is pared 10o about the time that the main paring-knife has passed half-way around the apple, or, in other words, the supplemental knife acts upon the stem end of the apple at the same time that the main knife is acting upon the blow end, and the knock-off previously described is so timed in relation to these parts as to operate after both knives have acted. upon the apple and previous to their coming into proper position for a repeated operation.

By making the two paring-knives act simultaneously upon opposite ends of the apple and prior to the action of the knock-01f, there is no danger of having the apple removed from the fork before the knives have finished their work. Were it not for the above arrangement of the parts the apple would be liable to be knocked off by the action of the stem-paring knife before it was pared at the stem end.

I claim as my invention- 1. The combination of suitable driving mechanism, the knock-off 0, arranged to slide longitudinally upon the fork-shaft, and provided with the arm 0, the fork b and its shaft, mounted in stationary bearings, and the rotary wheel F, provided with the revolving cam g, acting directly against the arm 0 of the knock-off at regular intervals during the continuous forward rotary movement of the forkshaft, substantially as described, and for the purpose specified. I

2. The combination of the knock-off 0, arranged to slide longitudinally upon the forkshaft, and provided with the arm 0, the fork I) and its shaft, the pinion D, driving-WheelB, pinion E, and wheel F, bearing the revolving cam g, which acts directly against the arm 0, substantially as described, and for the purpose specified.

3. The combination of the knife-carrier G and its cam r with the stem-paring knife J, mounted upon the stationarycam over the knife-carrier and inside of the circle described by the earn 1, substantially as described, and for the purpose specified.

4. The combination of the knock-off a, hearing arm 0, the fork b and its shaft, pinion D, driving-wheel B, pinion E, wheel 1*, bearing cam g, pinions m and n on shaft 0, the knifecarrier Gr, spring-actuated knife H, and cam r, mounted thereon, the stationary cam l, and the stem-paring knife J, substantially as described, and for the purpose specified.
